Short Latency Gray Matter Changes in Voxel-Based Morphometry following High Frequent Visual Stimulation
Magnetic resonance imaging studies using voxel-based morphometry (VBM) detected structural changes in the human brain within periods of months or weeks. The underlying molecular mechanisms of VBM findings remain unresolved. We showed that simple visual stimulation by an alternating checkerboard leads to instant, short-lasting alterations of the primary and secondary visual cortex detected by VB...
متن کاملRegional gray matter changes in major depressive disorder: an optimized voxel-based morphometry study
Introduction Voxel based morphometry (VBM) is a neuroimaging analysis technique that allows investigation of focal differences in brain anatomy, using the statistical approach of so-called statistical parametric mapping [1,2]. Major depressive disorder (MDD) is a common and serious psychiatric illness. In past study, the authors have done many researches to reveal the change in grey matter [3-7...
متن کاملVoxel-based morphometry in opera singers: Increased gray-matter volume in right somatosensory and auditory cortices
In contrast to instrumental musicians, professional singers do not train on a specific instrument but perfect a motor system that has already been extensively trained during speech motor development. Previous functional imaging studies suggest that experience with singing is associated with enhanced somatosensory-based vocal motor control. However, experience-dependent structural plasticity in ...
متن کاملAdjusting for global effects in voxel-based morphometry: Gray matter decline in normal aging
Results from studies that have examined age-related changes in gray matter based on structural MRI scans have not always been consistent. Reasons for this variability likely include small or unevenly-distributed samples, different methods for tissue class segmentation and spatial normalization, and the use of different statistical models. Particularly relevant to the latter is the method of adj...
متن کاملVoxel-based morphometry shows no decreases in cerebellar gray matter volume in essential tremor.
OBJECTIVE To investigate cerebellar gray matter volume in patients with essential tremor (ET). METHODS We used voxel-based morphometry (VBM) based on high-resolution T1-weighted MRI to compare gray and white matter density between 27 patients with ET and 27 age- and sex-matched healthy control subjects. Fourteen patients had only postural tremor, whereas 13 patients showed additional intentio...
